It seems that Latex does number equations in a depth first manner in nested footnotes. However it doesn't process the nested footnote, at least not in the example below! David Foster Wallace would not approve.
Anyone know how to get that to work?

More text. And another equation.
\begin{equation}
\sigma^{2}_{sp}=\sigma^{2}_{A}+\sigma^{2}_{B}-2\sigma_{A}\sigma_{B}\rho

Apropos of nothing in particular you have made me wonder how latex will number equations in footnotes.
Worth a quick experiment...
Rule #1: Always number the pages of your manuscript!
Rule #2: Always number the equations on the numbered pages of your manuscript.
